MACHINE FOR BLOWE NG GLASS.

SPEGIFICATKGN' forming part of Letters Patent No. 453,795, dated June 9, 1891. Application filed February 2, 1891 Serial No. 379,873. (No modehl To and whom ff may concern:

Be it known that I; CHARLES LAVENDER STARTUP, a citizen of the United States, residing at lfll-lenville, in the county of Ulster and State of NewYork, have invented certain new and-useful Improvements in Machines for lllowing Glass; and I do hereby declare the following to be a full, clear, and exact description of the inventiornsuch as will enable others skilled in the art to which it apperiainsto make and use the same.

My invention relates to that class of ma chines in which a blast of air artificially produced is used to blow glass into various hollow shapes,and will be hereinafter more particularly described and claimed.

in the drawings, Figure 1 is 'a perspective view of a machine embodyingmy invention. Fig. 2 iso central and vertical section of the same; Fig. 3 is .a detail sectional view of the mold and parts adjacent thereto. Fig. -'l is a bottom view of the parts illustratedin Fig. 3.

Various attempts have been made to design machines for blowing glass into simple forms-:sueh as bottles-by the use of an airblast other than that derived from the lungs of the operator; but none of these, so far as I know, have been capable of practical use.

My invention is designed to overcome the diiiieulties heretofore encountered by combining with the action of the blastamechanical action upon the body E the molten glass tending to assist the action of the blast, and in certain details ofthe construction embodied in the machines illustrated, in which-'- 1 represents the upright posts, and 2 the cross-bars of anyproper frame restingon the legs'fl. Mounted in this frame is a mold 4, which is preferably made in two parts and bolted together, as shown in Fig. 1. The upper portion of this mold is made in due or more parts 5, which are hinged to the stationary portion oi? the mold and may be swung over so as to open the mold by the action of the lever 18, the link 22, the crank-shafts 19, crms 20,'and the links 21, or by some equivalent arrangement of links and levers.

When the two portions 5 5 of the mold are closed, being held in position by the projecting lugs 6 6, the mouth of the mold may he closed by inserting the air-nozzle 24. This trols the motion of this slide.

opening 26 into the interiorof the mold when ever the spindle 28 is drawn up, as shown in Fig. 3. hen the spindle 28 is forced down, as shown in Fig. 1, it protrudes through the nozzle 24 and shuts off the supply of air through the air-ductBT. tached to the frame 31, which slides up and down in the. guide 30, which fits into grooves 1-1.

The plunger 0 furnishes a movable bottom to the mold 4. This plunger is controlled by the lever 13, which is pivoted to a. projection 1 on the plunger. 'ihisleverlllhasaconuterweight 14 and. an adjustable stop consisting of thesorew 12, mounted on the shank projection 11; In the plunger 9 is mounted the .screw 10, which'may be twisted or partially rotated by the crank 16 and therod l7 connected thereto, as clearly shown in the drawings. The adjustable stop 12 rests upon the block 23, and thereby limits the downward motion of the plunger.

The operation of my invention is the following: lhe plunger 9 heiugin its lowermost position, as shown in Figl-Ll and 3, or being in a still lower position than is there illustrated, the right quantity of glass at the right J temperatu re, sons to renderit pasty, is placed in the mold, the hinged portions of which are thrown back, as shown in Fig. 1. The lever 18 is then thrown up and the mold closed. The plunger 9-is.then forced up by the pressure of the operators feet on lever 13. The screw is given a partial rotation by means of the rod 17, and thereby forced into the mass of glass 8, which has been forced into the upper end of the mold. The nozzle 24 and the spindle 2S projecting through the same, are then forced down into the mouth of the mold and part way into the mass of glass. The plunger 9 is t ion drawn down, either' by its The nozzle 2% is atforce,-and the mass of glass Sbeing heldby in said piunger and" capable of being indeliho-screw is thus drawn out.
